  [First Embodiment]

  FIG. 1 is a perspective view showing an average platform in the first embodiment of the present invention.

  Referring to the drawing, the balance table 1 includes one beam portion 10 and two support leg portions 30a and 30b (sometimes referred to as the support leg portion 30 without distinguishing them). The balance table 1 is used, for example, with the support leg 30 grounded on the floor surface.

  The beam portion 10 is configured by assembling a marble 11 (an example of a protruding portion) 21 and a front (an example of a protruding portion) 23 on a log 11. The log 11 is formed using natural wood (natural wood) such as cedar. The beam portion 10 has a cylindrical shape. Here, the columnar shape includes not only one having a circular cross section but also one having a substantially circular cross section such as the beam portion 10. As the log 11, for example, a so-called polished log or a drawn log is used. Of the outer peripheral surface of the log 11, the parts other than the parts processed as follows are almost unprocessed, and the texture of natural wood is maintained. In addition, in FIG. 1 and the following figures, illustrations such as patterns that appear when the logs 11 use natural wood and surface irregularities are omitted.

  FIG. 2 is a perspective view showing an averaging platform viewed from the bottom side.

  Referring to the figure, a log 11 is provided with a so-called back crack 13. The back crack 13 is open toward the lower side of the balance platform 1. The back crack 13 is formed over the entire length of the log 11 so as to open to both ends 11 a and 11 b in the longitudinal direction of the log 11. By providing the back crack 13, the log 11 is prevented from cracking.

  With reference to FIG. 1, the upper portion of the log 11 is cut substantially flat along the longitudinal direction of the beam portion 10. Thereby, the flat part 15 which is a cutting surface is provided in the upper part of the beam part 10. As shown in FIG. The flat portion 15 is provided on the upper portion of the beam portion 10 by cutting and removing a part of the outer peripheral surface of the log 11. The flat portion 15 is provided on the upper portion of the beam portion 10 over the entire length direction of the beam portion 10. The flat portion 15 is formed so as to be substantially parallel to the floor surface when the balance table 1 is grounded to the floor surface. The user can get on the upper part of the beam portion 10 including the flat surface portion 15 and can play an average platform game using the average platform 1.

  In the present embodiment, three marbles 21 and three fronts 23 are provided. Each marble 21 and the front 23 are embedded in the flat portion 15 of the log 11 as described below. The marbles 21 are arranged such that their hemispherical portions protrude from the flat surface portion 15. Hajiki 23 is arranged so that one surface thereof protrudes from flat surface portion 15. As the marbles 21 and the Ohaji 23, for example, those made of glass having various colors are used. Since the light is reflected by the marbles 21 and the repellent 23, the balance beam 1 has a characteristic appearance.

  In the plane portion 15, marbles 21 and repellents 23 are arranged in a line. Each of the marbles 21 and the repellent 23 has a marble 21 and a repellent from the one end (the end on the original side (root side)) 11a side of the log 11 toward the other end (the end on the end side) 11b. 23, marbles 21, marbles 23, marbles 21 and marbles 23 are arranged so that marbles 21 and marbles 23 are alternately arranged at substantially equal intervals.

  As shown in the figure, the support leg portion 30 is disposed in a portion of the beam portion 10 close to both end portions 11 a and 11 b of the log 11. That is, a support leg 30a is provided near the end 11a on the original side of the log 11, and a support leg 30b is provided near the end 11b on the end side. The support leg 30 is formed using a natural wood solid material.

  When the balance platform 1 is viewed from the end portions 11a and 11b of the log 11, the support leg portion 30 is configured to project to both sides of the beam portion 10 so that the beam portion 10 can be supported firmly. Of the upper surface of each support leg 30, the corner of the side away from the beam portion 10 is chamfered so that a relatively sharp corner does not come into contact with the user who uses the balance table 1.

  Referring to FIG. 2, two anti-slip plates 31 are attached to the bottom surface of each support leg 30. The anti-slip material 31 is, for example, a rubber plate having a thickness of about 2 mm. The balance platform 1 is grounded to the floor surface via a non-slip plate 31. By attaching the anti-slip plate 31, even if a force that shifts the average platform 1 laterally with respect to the floor surface is applied in a state where the average platform 1 is grounded to the floor surface, the average platform 1 is It is difficult to displace. Thereby, the average stand 1 can be used without paying attention to the positional deviation of the average stand 1. Moreover, when the anti-slip plate 31 is attached, when an impact is applied to the balance platform 1, the impact is not directly transmitted to the floor surface, but is buffered by the anti-slip plate 31 and then the floor surface. Is transmitted to. Therefore, noise and vibration when using the balance table 1 can be reduced.

  The anti-slip plate 31 is not limited to a rubber plate, and may be a sheet formed of, for example, a sponge-like resin. Further, instead of the anti-slip plate 31, so-called rubber feet may be attached to the bottom surface of the support leg 30.

  Each support leg 30 has two through holes 35 formed so as to penetrate from the bottom surface to the top surface. Each support leg 30 is assembled to the log 11 by inserting a bolt (not shown) upward from the bottom surface side of the support leg 30 so as to penetrate the through hole 35 and tightening the bolt to the log 11. Yes. The bolts are fastened to the respective parts on both sides of the back crack 13 when the log 11 is viewed from the bottom side of the log 11, and the support leg portion 30 is fixed to the log 11 so as to straddle the back crack 13. . In addition, the bolt which couple | bonds it and the log 11 about one support leg part 30 may be one, or may be three or more. In addition, the support leg portion 30 has all the bolts that couple it to the log 11 being tightened to one side of the log 11 with the back crack 13 as a boundary when the log 11 is viewed from the bottom surface. You may make it the effect by providing being demonstrated more reliably.

  FIG. 3 is an exploded perspective view of the balance table 1.

  With reference to the figure, the marbles 21 and the front 23 are disposed in the holes 17 formed in the flat portion 15 and embedded in the log 11. Each of the marbles 21 and the front 23 is fixed to the log 11 by, for example, adhesion.

  In addition, the chamfering is given to the corner | angular part of each part of the average stand 1. FIG. Thereby, a favorable touch is obtained when a user contacts.

  FIG. 4 is a side view showing the balance table 1 in a state of being grounded on the floor surface.

  Referring to the drawing, since log 11 is a natural wood, the dimensions of both end portions 11a and 11b thereof are different from each other. In the present embodiment, one end 11a is the original (original) side close to the root of the tree, and the opposite end 11b is the end (end) close to the tip of the tree.

  Here, the beam portion 10 has a support leg portion so that an upper end edge (indicated by a two-dot chain line in the drawing) of the log 11 is parallel to the floor surface in a side view in a state in which the balance platform 1 is grounded to the floor surface. 30. Here, the phrase “parallel to the floor surface” includes the case of being substantially parallel. Moreover, the upper end edge of the log 11 means an upper end edge when it is assumed that the upper part of the log 11 is not cut and the flat portion 15 is not provided.

  For example, the diameter of the end 11a of the log 11 is d1, and the diameter of the end 11b is d2. Since the end portion 11b is the end side, the dimension d2 is generally smaller than the dimension d1. That is, the end portion 11b is thinner than the end portion 11a. Therefore, the dimensions of the supporting leg portions 30a and 30b and the log 11 are approximately d1 when the supporting leg portion 30b supports the vicinity of the end portion 11b rather than the height at which the supporting leg portion 30a supports the vicinity of the end portion 11a. It is set to be higher by the difference of d2. Since the support height of the support leg 30 is set in this way, the upper portion of the log 11 is substantially parallel to the floor surface even when the flat portion 15 is not provided on the upper portion of the log 11.

  In the present embodiment, the upper surface of the log 11 is cut into a substantially uniform width over the longitudinal direction of the log 11 and the outer peripheral surface of the log 11 is removed, so that the flat portion 15 is provided on the upper portion of the log 11. ing. In this state, the height of the flat portion 15 from the floor surface is H1, which is substantially equal over the longitudinal direction of the log 11. As described above, the plane portion 15 is formed so that the plane portion 15 is substantially parallel to the floor surface by adjusting the posture of the log 11 in accordance with the dimensions of both ends 11a and 11b of the log 11. The width dimension of 15 is substantially equal over the longitudinal direction of the log 11. Therefore, the appearance of the average platform 1 is improved, and the average platform 1 can be easily used as an average platform.

  FIG. 5 is a side view of the balance platform 1 as viewed from the end 11 b side of the log 11.

  With reference to the drawing, the width dimension W of the flat surface portion 15 is, for example, about 30 to 40 millimeters, and is formed to be considerably smaller than the general foot sole width of the user. For this reason, it is difficult for a general user to put his / her feet only on the flat surface portion 15 to achieve balance on the balance table 1. When the user uses the average platform 1 with bare feet or the like, the average platform having a conventional rectangular beam portion is brought into contact with not only the flat surface portion 15 but also the unprocessed outer surface portion of the log 11. Can be used in a different way. At this time, since the outer peripheral surface of the log 11 is applied to the user's foot, the sole stimulation effect is provided to the user's foot. In other words, in addition to the purpose of training the sense of balance, the average platform game using the average platform 1 can be performed for the purpose of obtaining the sole stimulation effect. Further, in the balance platform game using the balance platform 1, it is necessary to use the sole muscle strength by bringing the sole into contact with the raw outer surface portion of the log 11. That is, the user rides on the surface of the log 11, holds the log 11 at the three points of the thumb, the child's finger, and the buttocks, and applies a force to the sole so as not to fall while maintaining the balance. Therefore, when playing on the balance platform using the balance platform 1, it can be expected that the muscle strength of the sole will be improved and the inside vertical arch (arch) of the sole will be formed, and that the user will have flat feet. The effect to prevent can be expected.

  Note that the width dimension W of the flat surface portion 15 is determined according to the attribute of the user to be used on the balance platform 1, that is, for example, used by infants or used by school-aged children, or exclusively for adults. Depending on whether or not is used, it may be changed as appropriate.

  Moreover, an example of the dimension of each part of the average stand 1 is as follows. For example, the height of the flat portion 15 from the floor surface (dimension H1 in FIG. 4) is about 150 millimeters. The diameter of the log 11 is about 120 millimeters. The length of the beam portion 10 (log 11) in the longitudinal direction is about 1400 millimeters. In addition, the dimension of the average stand 1 is not restricted to this, For example, a thicker log may be used, and the length of the beam part 10 may be lengthened or shortened.

  The balance beam 1 can be used for various purposes besides performing balance beam games such as gymnastics and gymnastics games. For example, as one application, the user can sit on the beam portion 10 and use it as a long chair. Since the beam portion 10 is relatively long, a plurality of users can use it simultaneously. At this time, since the width dimension of the flat surface portion 15 is relatively narrow as described above, the user needs to keep his / her waist while maintaining his / her balance. Therefore, a balanced training effect can be obtained.

  Moreover, the balance beam 1 can be used for the implementation method of the health method from which the massage effect similar to what is called a bamboo bamboo step is obtained. That is, since the beam portion 10 of the balance table 1 uses the log 11, the outer peripheral surface of the beam portion 10 is roughly cylindrical. Therefore, the user can stimulate his / her foot by putting his / her foot on the upper part of the beam portion 10 in the same manner as the so-called bamboo bamboo stepping.

  As described above, in the present embodiment, the balance stand 1 is configured using the log 11 of natural wood. Therefore, when used as a balance stand for gymnastics competition or gymnastics play, Can be used in a slightly different way. In addition, the balance platform 1 can be used as a long chair as described above, or can be used as a so-called bamboo bamboo tool, and can be used for various purposes in various ways.

  Since the marble 21 and the front 23 are arranged on the flat surface portion 15, when the user uses the average platform 1 as the average platform, the average platform so that the soles are stimulated by the marble 21, the front 23, and the like. By being placed on 1, the sole stimulation effect can be obtained. In addition, when the balance platform 1 is used as a so-called bamboo bamboo stepping tool, the user can obtain a stronger local foot stimulation effect as compared with the case where the bamboo bamboo stepping is simply performed.

  As described above, each part of the balance table 1 is a solid wood, and the surface of the balance table 1 is not coated with varnish or lacquer. Therefore, it is possible to obtain a soft and comfortable wood feel when the user rides on the balance platform 1 barefoot. In addition, since the balance platform 1 exhibits moderate hygroscopicity, even if the user's soles are moistened or water droplets adhere to the balance platform 1, the user is less likely to slip, and the balance platform 1 should be used comfortably. Can do.

  [Second Embodiment]

  In the second embodiment, the shape of the flat surface portion in the beam portion and the presence / absence of a marble or a fly differ from the first embodiment. Since the configuration of the other parts of the balance beam in the second embodiment is the same as that in the first embodiment, the description here will not be repeated. Hereinafter, the same components as those described in the first embodiment are denoted by the same reference numerals, and detailed description thereof is omitted.

  FIG. 6 is a perspective view showing an average platform in the second embodiment.

  Referring to the figure, the balance platform 101 has a beam portion 110 configured using a log 11 and two support leg portions 30a and 30b that support the beam portion 110.

  The beam part 110 does not have the marbles 21 and the repellency 23 as compared with the beam part 10 of the balance table 1 in the first embodiment described above. Further, the beam portion 110 has flat portions 115 a and 115 b partially formed on the upper portion of the log 11 instead of the flat portion 15 formed in the entire region in the longitudinal direction.

  The flat part 115 a is formed in the upper part near the end 11 a on the original side of the log 11 by cutting the upper part of the log 11 and removing a part of the outer peripheral surface of the log 11, similarly to the flat part 15. . The flat portion 115b is formed in the upper part near the end portion 11b on the end side of the log 11 in the same manner as the flat portion 115a. The length in the longitudinal direction of the beam portion 110 of the flat portions 115a and 115b is, for example, approximately the same as the user's foot length (approximately 150 to 300 millimeters) or approximately the same as the user's foot width (approximately 100 millimeters). be able to.

  As described above, in the second embodiment, the flat portions 115a and 115b are provided only in the vicinity of the end portion of the upper portion of the beam portion 110, and the outer peripheral surface of the log 11 remains as it is in the other portions. It is left. Therefore, the user can use the balance table 101 by a different method depending on the part on the beam part 110. That is, the user can maintain a balance relatively easily when he / she is standing or sitting on the flat portions 115a and 115b. On the other hand, when riding on a portion where the outer peripheral surface of the log 11 remains as it is, it is difficult to maintain the balance, and more advanced technology is required to maintain the balance. Therefore, the user can obtain the training effect of the balance sensation with different degrees depending on the part of the ride. Further, when the user rides on the part where the outer peripheral surface of the log 11 remains as it is, the entire surface in contact with the sole becomes a curved surface, and thus the user can obtain the same effect as the so-called bamboo bamboo step more strongly.

  Since the flat portions 115 a and 115 b are formed in the vicinity of the end portions 11 a and 11 b of the log 11, the user can get on the beam portion 110 relatively easily from the end of the average platform 101. The user can first get on the beam portion 110 and move to a portion where the outer peripheral surface of the log 11 that is more difficult to maintain balance is left as it is in a state where the posture is adjusted.

  In the second embodiment, a plane portion may be formed in a portion different from the above, and the dimensions of the plane portion may be changed as appropriate. Further, the number of flat portions provided partially may be one, or may be three or more.

  FIG. 7 is a perspective view showing an average base 201 according to a modified example of the second embodiment.

  Referring to the figure, the average base 201 has a beam portion 210 having a number of plane portions different from that of the average base 101. A plane portion 215 is partially formed on the upper surface of the beam portion 210. The flat part 215 is formed by cutting the upper part of the log 11 and removing a part of the outer peripheral surface of the log 11 in the same manner as the flat part 15 in the first embodiment described above. The flat portion 215 is formed at seven locations in the upper part of the log 11. The length in the longitudinal direction of the beam portion 210 of the plane portion 215 is, for example, about 200 millimeters. That is, on the upper part of the beam part 210, the plane part 215 from which the log 11 is cut and the part where the outer peripheral surface of the log 11 is left as it is are formed alternately along the longitudinal direction of the beam part 210. Yes. In other words, the beam portion 210 is such that the outer peripheral surface of the log 11 is partially left as it is above the beam portion 210. The beam portion 210 is not provided with marbles or repellencies.

  As described above, since the planar portion 215 is partially provided on the beam portion 210, the user can obtain substantially the same effect as that of the above-described first embodiment, and the average stand 201 can be used in various ways. Can be used. For example, when the user crosses the balance platform 101, the user can select a difficulty level for maintaining balance by selecting one of the flat portion 215 and the other portion as a portion to get on, and obtain different training effects. In addition, the user can obtain a stronger foot stimulation effect by riding on the stepped portion between the flat portion 215 and other portions.

  In the balance table 201, the longitudinal dimension of the log 11 of each flat surface portion 215 is increased so that the portion where the outer peripheral surface of the log 11 is left as it is partially protrudes upward from the flat surface portion 215. May be. Thereby, even if it does not provide a marble or a front, similarly to the case where they are provided, the user can obtain a relatively strong sole stimulation effect at a pinpoint. Further, the size of the log 11 in the longitudinal direction between the flat portion 215 and the portion where it is not formed is reduced, and the portion on which the user on the beam portion 210 rides is serrated along the longitudinal direction of the log 11. A jagged surface may be formed.

  [Others]

  You may comprise an average stand combining each characteristic part of the above-mentioned embodiment. For example, in the first embodiment, the marbles and the hajiki may not be provided.

  In the second embodiment, marbles or hajiki may be embedded in logs. Thereby, a higher sole stimulation effect can be obtained. Marbles and Ohajiki are not limited to the flat portion, and may be embedded in a portion where the outer peripheral surface of the log is left as it is.

  Further, the protrusions provided on the log are not limited to marbles or Ohajiki. For example, it may be stone or resin. Further, for example, leaf-shaped glass beads, flower-shaped glass beads, or other glass balls may be attached to the log as protrusions. The protrusion part should just be provided so that it may protrude from the surface of a log.

  The dimensions of logs, the number and dimensions of support legs, or the number and arrangement of marbles and repellents are not limited to those described above. For example, the height from the floor surface to the upper part of the beam part may be changed by changing the thickness of the log or changing the height of the support leg part. You may distinguish the site | part in which a marble is arrange | positioned among the beam parts, and the site | part in which a sushi is arrange | positioned. For example, a marble may be arranged near the end of the beam and a fountain may be arranged in the center so that a changing balance beam game can be performed.

  The plane portion may not be generated at all in the beam portion. Moreover, the beam part should just be comprised by the outer peripheral surface of the log at least one part among the surfaces of the part which the user who got on the beam part can contact the upper part of the beam part, and other parts are logs. It does not need to have an outer peripheral surface. Since the user touches the outer peripheral surface portion of the log, the balance can be used for various purposes such as so-called green bamboo stepping in addition to the balance platform. Moreover, in the balance platform game, the improvement of the muscular strength of the sole and the formation of the inner vertical arch (arch) of the sole can be expected.

  The above embodiment should be considered as illustrative in all points and not restrictive. The scope of the present invention is shown not by the above description but by the scope of the utility model registration request, and is intended to include all modifications within the meaning and scope equivalent to the scope of the utility model registration request.
